How can fossils be used to show the history of life on Earth?
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
What information do fossils provide about the history of life?
By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments.
What is the role of fossils in the history and origin of the earth?
Fossils are physical evidence of preexisting organisms, either plant or animal. Fossils of any kind are useful in “reading the rock record,” meaning they help us decipher the history of the earth. They can help us determine the geologic age and environment (the paleoenvironment) in which they were deposited.
How do fossils provide important clues to environmental changes that occurred in Earth’s past?
about the geologic history of Earth. How do fossils provide important clues to environmental changes that occurred in earths past? an index fossil discovered in rock layers in different areas of the world indicates that the rock layers in these areas formed during the same time period.
How can fossils be used to provide evidence of how life and environmental conditions on Earth have changed?
Fossils give clues about environmental changes where the organism lived, fossils can be used to date the time period of rocks and rock layers when the organism lived, fossils can give clues of changes in the organism’s body structure over time.
What do fossils teach us?
Fossils teach us about the history of life. A trace fossil is an example of mineralised bones and teeth. Amber is an insect found fossilized in rocks. Footprints on the beach are examples of trace fossils.
What do fossils tell us?
Fossils tell us which plants and animals existed in prehistoric times, and where they lived. They also tell us something about when they lived. Based on the position of fossils in the layers of the Earth’s crust, paleontologists can determine which animals predate other animals and which animals lived at the same time.
What do fossils show?
Fossils show us where animals lived and what size they were. That lets us know something about the past conditions on earth. When we see fish fossils on top of a mountain, for instance, we know that mountain is one that rose up later in time and that it used to be under water.
